:WhGIl frequent passage from .the pantry lto :the dining room and return isfrequire'd, the necessity for constantly pushing back the door for passage through .the .doorwaybecomes a distinct annoyance, particularly when the butler is carryingchinalorsarticles of foodin hisi handsh As a consequence, itis common. for the ,door to. be opened .intolone. .orthe other room and there retained to .pergmit unimpeded passage through the door- -way; The objection to this,: ofeourse, is that it permits unobstructed or freevision from one room to theother. m r. V To .remoyezthe foregoingxobjeotion, nay-inyention oomprehends hinging toltheltreeedge {:0f the unain door .a. second or J screen L door 5, f shown best in Fig. 2, the hinges being indijcated at 6: Thissoreenydoor is shown hinged *to the usual. face .of the main door 3, but it mightibe letinto the latter or otherwise more closely compacted therewith ii desired.

The door 5 preferably is rOVided Wi'th' means for retaining it in fully openfposition, for example, as shown in='"F-ig. Q WhBIG it stands at rightangles tothe n1 dobnB, andthis may conveniently be had hy employing a'type of hinge 6, such as illustrated 'in 11g; 3, wherein the contacting faoes "of-two 1 of the knuokles of the hinge 'are beveled as indicated at 7, Figs. 3 and eywhereb when g I the screen door is closed against the lIliLlIli 1.

door, as in dotted lines, Fig *2, the swinging ofone' inclined hinge, f aceji upon the iother, will. raise one hinge le'af withielatio to the other, andthereby raise the screendoor itself,

? knuckles in Fig; 3 but, whenthe sc'reen door is released to be opened to or toward iflts full 1 lineposition, Fig. 2, its weighty-lactingu on the inclined hinge facesi, willjcau'se the nor automatically to swing intojits fu lly opened;

position whatever particular position that will remain in @its fully openedg :positiomt asindieated by the separation of the hingecn maybe; until the elevated hingeknuokle g-ra V- h Such a doorso hung upon hinges ofthis -description is well-known inwthe :art and is 1 Conveniently the beveled contacting faces of the hinged knuckles at 7 embrace about onehalf the full circumference of the hinged knuckles at that point, the knuckles beyond that presenting horizontal faces 8, see Fig. 4, to furnish ample bearing for the knuckles when sustaining the screen door in its fully open position.

To retain the screen door in its closed position against the main door 3, as in dotted lines Fig. 2, any suitable latch orlocking device may be employed. In the present instance I have shown a conventional spring latch 9 arranged in a socket 10 let into the edge of the screen door, the socket containing a spring 11 which presses the latch 9 normally and yieldingly outward to the limit imposed by the head 12 upon the shank of the latch. This spring-pressed latch engages a suitable opening 15 in a striker or latch plate 14, secured by screws 15 or otherwise upon the face of the main door.

In use and under normal conditions, the screen door is closed against the face of the main door and there held by engagement of the spring latch with the striker plate 14, in which condition the two doors operate as a single door and may be swung freely in either direction upon the hinges 4, which latter bring the same normally at all times back to mid position, closing the doorway.

l/Vhen, however, it becomes desirable to open the main door to avoidthe annoyance of frequently opening and closing it during serving periods, the main door may be opened, as shown in Fig. 2, and there held as described, and then the screen door may in turn be opened upon the main door into its full-line position, Fig. 2-, whereupon a perfectly free and unobstructed passage is provided through the doorway, as indicated by the arrows, Fig. 2, while at the same time the screen door obstructs direct vision from one room to the other, and so provides an effective screen coupled with a free and open passageway.

The screen door may be of any. desired height, less or shorter than herein shown, and

may be made of any desired material, so as to furnish a complete obstruction ofvision, or only a partial one, as desired.

My invention is not limited to the particular embodiment disclosed.

5. The combination with amain door of a view obstructing door hinged to the free edge of said main door and openable toward the passage side of said main door when the latter is open for obstructing the view through the door opening and having means to retain it in open position relative to and upon said main door. I V i i 6. The combination with a main door of a View obstructing door hinged-to the free edge of said main door and having means to retain it in open or closed position relative to and upon said main door, said view obstructing door extending, when in open position, transversely with respect to said main door at the passage side thereof.

7. The combination with a main door of a view obstructing door hinged thereto and with means automatically to urge it toward open position and means to retain it in closed position upon and relative to the main door,

said view obstructing door extending, when in open position, transversely with respect to said main door and at the passage side thereof, in spaced relation to the door opening.

The combination, for the purpose described, of a main door and a supplemental door movably mounted thereupon and adapted to either lie flat therewith or be extended laterally with respect to said main door on the passage side thereof and spaced from said door opening, for obstructing the view through the door opening, while allowing passage therethrough.

9. The combination, with a main door positionable at substantially right angles to its door opening, of a supplemental door carried by said main door and positionable at substantially right angles to the planeof said main door and in front of and spaced from said door opening, whereby the positioning of both doors as aforesaid will obstruct the 1 a View through said door opening while allowname to this specification.
